VidGrid Interactive Installation

Project VidGrid

VidGrid was a short 10-day project in David Tinapple’s AME598 Media Installations class. This project uses an OptiTrack motion capture suite and projected video to present an introduction of the class. The 40+ students in the class each made two introductory videos each that are laid out in a grid. When the user moves around, the video under them changes to a different video track.

The Proposal:
Project VidGrid (Joshua, Varsha, Henry, Prashanth & Connor)

The goal is to make a pleasant if somewhat creepy experience of the class staring at you. As one navigates through the space, the students they are directly facing will introduce themselves.

Project VidGrid is an installation using motion-capture and two selections of student video. It will consist of a projected grid of student face videos that align to a person walking through the space. When they stop over a grid space, the eight videos around them switch to the student introduction videos, all oriented to the user.

The positioning will use the B127 Optitrack motion-capture system and ceiling-mounted floor projector combined with a laptop running the video application. The application will be a combination of Processing and any other glue logic needed. Given enough time/CPUs/luck, the tiles of each video will be projected in 3D OpenGL code so that they appear to follow the user. The plan is to provide baseball caps rigged for motion capture to provide 6DOF head tracking of users. An attempt will be made to make the system multiuser but this is unlikely.

This project builds on several team members experience in AME598 Understanding Activity in using the motion capture rig in B127.
